This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

Priority findings

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Sprachenatelier Berlin holds a strong market position as a recognized language school in Berlin, offering a wide range of language courses and cultural programs. Their competitive advantage lies in their extensive language offerings, flexible course formats (on-site and online), and recognized certifications. Revenue streams likely include course fees, exam fees, and cultural program participation. The target customer segments are international students, expatriates, professionals, and language enthusiasts. The school maintains an active partnership ecosystem through certifications and cultural collaborations. Strategic observations include leveraging their Berlin location and cultural integration to enhance the learning experience and expanding online offerings to capture a broader audience.

Security posture

The current security maturity level is moderate. HTTPS is enforced, and no sensitive data is exposed in the website content. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. There is no visible vulnerability disclosure or incident response information, which limits transparency and readiness. GDPR compliance is partial due to the lack of a cookie consent mechanism. The use of multiple analytics platforms increases tracking but is not balanced with clear privacy controls. Overall, the security culture appears basic with opportunities for improvement in policy transparency and technical controls.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to ensure GDPR compliance.
  2. Add and configure security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish explicit security and incident response policies to improve transparency and readiness.
  4. Review and optimize analytics usage to balance user tracking with privacy considerations.
  5. Conduct regular security audits and update technical infrastructure to maintain a strong security posture.

Technical notes

Notes

The website uses a mature CMS (KONTEXT-CMS) and integrates common web technologies such as jQuery and FontAwesome. Analytics are implemented via Google Analytics, Google Tag Manager, and Matomo, indicating a layered approach to data collection. The site is mobile-optimized and SEO-friendly with proper meta tags and structured data (JSON-LD). Hosting is stable with consistent DNS records. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of modern security headers and cookie consent mechanisms indicates some technical debt and compliance gaps. Overall, the technical infrastructure supports the business needs but would benefit from modernization and enhanced security controls.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
